Ligand Definition. A ligand is an atom, ion, or molecule that donates or shares one or more of its electrons through a covalent bond with a central atom or ion. It is a complexing group in coordination chemistry that stabilizes the central atom and determines it reactivity.
Ligand electrons repel d electrons [edit]. Ligands have lone pairs of electrons that they use to bond to transition metal atoms or ions. The presence of these ligand electrons repels the transition metal's electrons in its d orbitals.igands split d orbitals [edit]. Without ligands, all five d orbitals have equal energy. A complex needs ligands to be coloured. Without ligands, all five d orbitals are equal in energy (degenerate is a word often used here â it simply means of the same energy).
